Thread revival!
I'm about to get coilovers and hesitating between spring rates.
These coilovers come stock for the 06sti with 6kg/5kg f/r...
Going to up them a bit for my use...

What's a better combo 8/6 or 8/7 ... was thinking 8/7 to keep them within the same f/r kg difference as the off the shelf unit.

This coilover's full racing unit with external reservoir comes with 10/8 and the soft street version 6/5 .... thought 8/7 is good middle ground?
